Abstract

Diagonal deep well region for routing the body-bias voltage for MOSFETS in surface well regions is provided and described.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention generally relates to MOSFETS (metal oxide semiconductor field effect transistors). More particularly, the present invention relates to the field of routing body-bias voltage to the MOSFETS.[0003]2. Related Art[0004]Generation of the physical layout of a semiconductor device having MOSFETS (metal oxide semiconductor field effect transistors) formed on a semiconductor substrate is a challenging task. An extensive amount of time and resources are spent during the creation of the physical layout. However, consumption of resources can be minimized if new physical layouts utilize substantial potions of existing physical layouts. For example, a new physical layout having MOSFETS that are body-biased would be less expensive to generate if an existing physical layout having MOSFETS without body-bias is utilized and modified according to the needs of the new physical design. Unfortunately, this process of mo...

Generation of the physical layout of a semiconductor device having MOSFETS (metal oxide semiconductor field effect transistors) formed on a semiconductor substrate is a challenging task.

An extensive amount of time and resources are spent during the creation of the physical layout.

Unfortunately, this process of modifying the existing physical layout typically requires forming an additional routing layer for the body-bias voltage on the surface of the semiconductor device, creating a serious issue since the existing physical layout utilizes most, if not all, available surface area.
